Abstract:

The long-standing problem of the great fluctuation in outlet temperature of the quench cooler A (L-101A) in the No.1 cracking furnace easily led to the coking during the secondary reaction of cracking gas and affected the subsequent system. The cooling medium of the quench cooler was replaced, the original process water was changed to purified water, and the actual data before and after the transformation was compared and analyzed. The outlet temperature of the quench cooler was stabilized by optimizing the cooling medium, and the decoking cycle of the quench cooler A (L-101A) in the No. 1 cracking furnace was prolonged.
